DTRACKSDK#
Properties
ARTTracker.ERROR LastDataError#
The data on the last received error.
int NumInertial#
The number of all tracked standard 6dof bodies (i.e. all 6dof bodies except flysticks, measurement tools, etc.) and all hybrid bodies.
int NumHuman#
The number of human models.
int NumHand#
The number of tracked hand bodies.
int NumMarker#
The number of tracked additional markers.
int NumMeaRef#
The number of defined reference bodies of the measurement tool.
int NumMeaTool#
The number of defined (calibrated) measurement tools.
int NumFlyStick#
The number of defined (calibrated) flystick bodies.
int NumBody#
The number of dtrack bodies.
double TimeStamp#
The time at the measurement of the current frame, i.e. the time when the infrared flash of the cameras is fired. the timestamp uses the internal clock of the controller, giving back the seconds (with an accuracy of 1μs) since 00:00 utc (midnight). this implies that the timestamp value is reset to zero when passing midnight (utc).
int FrameCounter#
The A frame counter (counting with synchronization frequency).
